Lumin NOW works with ROON

that is why it is confusing..when i hit the gears and then touch the 'disable' indicator the Airplay/Lumin section then says 'Enabled'....not disabled'''??

On the iPad I use, it says Enable not Enabled. Enable means "to enable this currently-disabled device". Yes it is confusing. :S

In the Roon ready/Lumin A1 section is there supposed to be a red 'Uncertified' label.?

We shipped a D1 for the certification process. It doesn't make sense for us to ship all models to certify, because many models run the same firmware binary. We're working with Roon Labs to clear up the certification display, but these things take time. Please do not worry about the red label.
 
I've talked to Roon Labs and they'll improve the setup flow for newly discovered Roon Ready devices in the future.

Hi Peter.
For three days I have a trial version of Roon with the Core installed on a PC (without audio optimization), which connects to the same switch as the NAS. After a generic cable Cat 7 of about 8 meters arrives until the room where is the Switch Aqvox and of this, a cable of 1,5 meters until the Lumin. I am playing the same audio files, hosted on the NAS! Sometimes from Lumin application therefore using Minimserver / UPnP and others using Roon / RAAT. My question is this; When a file comes from Roon / RAAT and reaches the Lumin, it goes through the same digital circuits before reaching the DAC Wolfson, that when it arrives until the Lumin by Minimserver / UPnP?. I am very intested in the answer, because what I am hearing is very rare.

So whats the verdict on Roon for you? As Peter asked is there a sound difference you are hearing?

Hi.
Since I sent that post, I have received my new Melco and a mini PC to have Roon core connected to the Aqvox switch. I am traveling for a few days, when I return and do a quiet listening, I will publish my impressions.

Let me start by saying thank you for the continued support by Lumïn. However after listening for the better part of a month to Roon against the proprietary software on my Lumïn S1, I've come to the conclusion, in my opinion, the Lumïn software sounds best.

Roon just doesn't sound as engaging to me or as quiet as Lumïn. Roon sounds a little bloated and not as precise to me.

For reference I've run Roon on Windows 10 pro, windows sever R2, and finally Linux which sounded best by far, but still lags behind Lumin's on software. Again just my opinion.

Hello,

For the past few days I have tried Roon on a dedicated Windows PC running Server R2. I have to say that I agree with Elem79, regarding comparisons between Roon and Lumin software. Although Roon recommend a dedicated QNAP NAS server, I would want some reassurance that this would sound better than my Lumin L1 with Kenneth Lau PSU.

I presume Lumin have done comparisons between a Roon NAS server and their own L1; it would be interesting to know their thoughts.

If I'm not mistaken, I think Roon Labs is encouraging people to use Intel NUC running ROCK instead of NAS:

Discussions about what hardware sounds best for running Roon:

This may come as a surprise, but SQ evaluation is not really part of my job. :lol: For Roon Ready certification, it is a requirement that devices playing from Roon give a sound quality equivalent to their native means of playback. Even if I were to hear anything different (I didn't), I would not be able to say it.

From a firmware point of view, it's the same lossless audio bits that go into the playback hardware. From a CPU and network processing point perspective, there is indeed higher CPU utilization and more network traffic when using Roon.

When comparing a high CPU power Roon server against L1 + LPS, the former is likely disadvantaged due to typically noisy PC power supply, considering that the NUC is probably not much more expensive than your LPS.

Roon Labs CTO says it'd be fine as long as you are "isolating it properly" - "Isolating audio gear from RFI/EMI is important regardless of anything else. This is why high quality power supplies and tools for filtering/isolating ethernet, USB, and line power make a difference."

I'm always interested in hearing users' thoughts regarding SQ.

Thank you for this Peter. To elaborate more on the PC I used, it is part of a two PC system I used with JPlay as my playback software. It has separate HDPlex linear power supplies. JPlay was my reference playback software for quite some time until I heard a Lumin A1. I was so impressed I bought the S1.
 
Hi Peter.
Do you know why Roon does not upsampling to 384 and 352.8 and only does it to 192 and 176.4, when Lumin can handle the higher frequencies?
 
That's a limitation with the current Lumin models (except U1).

(Just got back from vacation)
 
Hi Peter.
1. If I understood Lumin well (except U1) they can accept PCM files 352.8 and 384 for UPnP but not for RAAT. I would be curious to know the reason, if you can explain it.

2. It has an approximate date, in which Lumin decodes the MQA files
Regards
 
I'm sorry but that's a hardware limitation, and I cannot provide a date for public firmware release - this is something out of our control and more work needs to be done by both MQA Ltd. and us. On a slightly positive note, Lumin is demoing S1 playing MQA at Munich, after receiving blessing from MQA Ltd. for S1 audio quality for MQA playback.

Lumin U1 also supports 352.8kHz and 384kHz, as long as the DAC is connected via USB and the DAC itself supports these sampling rates.
 
Peter

I assume you are aware the Auralic, one of the original MQA partners, has now released their own version of "MQA" decoding.
 
For those who are using Roon, please upgrade Roon Core to Build 234, and Lumin to Firmware 8.04. The new Lumin firmware contains optimizations for Roon Build 234, and may possibly improve SQ.

Feedback on SQ for this upgrade is much appreciated. Thanks.
